Open Google Patents

This solution allows you to quickly open Google Patents for a selected issued patent identifier or pre-grant publication identifier.

Select a patent identifier in text, then open the context menu and select "Open Google Patents" from the menu. You can normally open the context menu by right-clicking. For example, selection of "US7654321," and then "Open Google Patents" from the context menu, opens a new tab to the URL https://patents.google.com/patent/US7654321.

The solution works for both issued patent identifiers (e.g., US7654321, EP1234567) and pre-grant publication identifiers (e.g., US20240011111). Because the solution uses the identifier in the corresponding Google Patents URL, it is NOT currently possible to use the patent application serial number (e.g., US18/123,456).

Note that in the absence of a country code prefix, the presumption is that the identifier is for a US patent document. Be sure that the identifier has the country code included if the associated document is not a US patent document.

The extension should work for any webpage loaded after the initial installation of the extension, as long as JavaScript is enabled.

Please let me know of any issues you experience before writing a review -- I'm happy to continue to improve the solution. The extension is provided 'As-Is' without any express or implied warranty of any kind.

Note that I do not collect any information from the extension -- all handling is done at your local browser.

Enjoy!
